Unit 2 Exam Flashcards
Name 3 Pelvic Landmarks and Quadrants
- Iliac Wings (crest)
- Umbilicus
- Symphysis Pubis
PELVIC CAVITY see pic 1
- Ill-defined area of body where the trunk meets the lower limbs
- Bony pelvis lies in close relationship to cavity
- Female and Male * reproductive organs are mainly located in this cavity
BONY PELVIS see pic 4
- Encloses a funnel – shaped cavity
- Inferior portion of Abdominopelvic cavity
- Divided into Pelvis major Pelvis minor
- Forms the funnel cavity
PELVIS MAJOR also known as the False pelvis
see pic 7,8,9,10
- Also called FALSE pelvis
- Space between iliac fossa and its inferior boundary
- Defined by pelvic brim
- Part of abdominal Cavity

**False Pelvis what organs are within?
Abdominal viscera: parts of small intestine Sigmoid colon and Abominal Muscles

What muscles are in the Major Pelvis, False Pelvis
Psoas Major and Iliacus Muscles
PELVIS MINOR ALSO KNOWN AS
The space below…..
True Pelvis
Most of the female reproductive organs lie here if Norm size
Space below the pelvic brim and enclosed by sacrum, ischium, pubis and portion of ilium

What does the true pelvis contain? see pic 8,9,10
- U-Bladder
- Rectum
- Internal reproductive organs
- Portion of mobile GI tract

What muscles are in the True Pelvic see pic 20, 21
- Obturator Internus
- Piriformis

PELVIS MINOR/FALSE PELVIS see pic 2
what divides them?
- I_maginary line divides the True from false pelvis_
- Extends from Symphysis Pubis to Sacral Promontory

What defines the Pelvic Brim
The False Pelvic
Bony Frame Work of Pelvis
Is formed by? see pic 11
- the sacrum
- the coccyx
- paired os coxae
- (Hip Bones)
THE SACRUM see pic 5
Along with the coccyx the sacrum makes up the posterior midline portion of the bony pelvis
Tips Posteriorly

Where is the Sacrum? see pic 6
- Articulates with L-5
- Tips posteriorly
- Angle formed called Lumbosacral angle
- Transmits with of the body to hip bones, then to lower extremities
- Normally five sacral vertebrae fuse into a triangle-like mass*
SACRUM see pic 5
Anteriorly the upper margin S1 forms the Sacral Promontory
This is the posterior landmark for the True Pelvis, inlet or pelvic brim
made up by the anterior sacral promontory
Is normally fused
Anterior surface of sacrum (pelvic surface) forms a concave curve
Sacral Formina
What is it? what goes through?
Where are the openings?
how many are they? see pic 5
- Both anteriorly and posteriorly are rows of four openings
- This is where nerves pass thru
- Posteriorly surface of sacrum between formina and and fused spinous process from the median crest
- S-5 has no spinal or lamina referred to as Sacral hiatus
- This is where an epidural injection occurs

Where is the COCCYX BONE?
Whats another name for the bone?
Where does it join?
Made by what?
fused by?
- most inferior portion of vertebral column
- Also called the tail bone
- Joined to sacrum by cartilage
- Usually made of 3-4 rudimentary (underdeveloped) vertebra
- usually fused by adulthood

Does the Coccyk Bone offers support?
Where does it attach?
- Offers no support to vertebral column
- Provides attachment for Gluteus Maximus muscle
- Provides attachment for pelvic floor muscles

Where is the OS COXAE see pic 3
what do each consist?
Innominate bones (paired) Lay person may refer to them as hip bones
Right and left ilium
Right and left pubis
Right and left ischium

Right and left ILIUM see pic 3
Is it the smallest? Largest?
Where is it?
What aspect is in it?
Where does it originate?
- Largest of the three bones of the hips
- Superior part of the Ilium presents a large, wing-like surface called the ala
- Inner aspect of the ala is the illiac fossa
- This is the origination of the iliacus muscle

What makes up the coccyk
is joined to sacrum by cartilage
its consist of four rudimentary vertebrae with no processes or foramina
Where is the Illiac crest? in the Ilium see pic 3
Iliac Crest, most superior portion of the Illium
its an Xray landmark

*What make up the pelvis?
Enclosed a funnel shape
Formed by
The Sacrum
The Coccyk
The Paired OS Coxae
The Hip bones
Whats Posteriorly in the Illium see pic 3
Posteriorly ilium articulates with sacrum at the Sacroiliac joint
